Poking the Bear Ford Performance Products

[Tom Dolan]

The only reason it was not in stock when it came out, there was no weight break for it to fit into. There was no FS/AA class. I don't know, but i don't think the 5.4 combo is better than a 5.2 just because the sc is bigger. I also don’t think most will agree when you say most will agree...duh. Its in the guide so I don’t know what your point is. This thread is about ford giving then taking it back for un know reasons. I wish someone from ford would come on here and tells us why, is that to much to ask.

your incentives for developing your racing program, or someone you were considering for driver/ sponsorship, are more limited. So are the resale value of these cars. Just simple, provable observations.

Doug,


Funny you say that, Mike D. worked for Dodge for 30 years and if you want free stuff from Ford you have to own a Dodge, race a Dodge, or build Dodge/Mopar engines.
